Hi.
Phil ,  how can I use  WTRLaunch.exe  outside from the server ?
How use it  inside   my dll ?
eg.   RUNSHELL(" /C START C:\ALASKA\WAA1W32\SERVWER\WTRLAUNCH.EXE",,.T. )

Best regards

If you mean from another machine, then you can't.  It can kill the process
remotely, but cannot restart it.

Yep, that should do it

Yes, I know that WTRLaunch.exe  run on sever, but  how  start it form
outside.
look at my prg.
in MYDLL.dll
...
function  killme()
RUNSHELL(" /C START C:\ALASKA\WAA1W32\SERVER\WTRLAUNCH.EXE", ,.T., .F. )
quit
return .t.
....
from outside

http://...../waa1gate.exe?WAA_PACKAGE=MYDLL&WAA_FORM=KILLME

after that   WAA  is closed  but not  correct.
WTRLAUNCH.EXE run  but can't  restart  WAA  , beacouse     one  proces
waa1gate.exe is open in memory on server.
Why  after quit    WAA not close correct.

That will launch WTRLaunch on your machine, not on the server, therefore
it cannot restart WAA.

I'm not sure - I've never come oacross this problem.  WAA always shuts down
correctly for me, even if I issue the KILLME call from my web-browser (BTW,
I use a very different function name that won't be discovered by accident
by a malicious user - e.g. WAA_FORM=KickMyButtAndMakeMeScreamQuietlyPlease)

Why  ?
All function in dll   works on the server   and after send   html to client

nice  name
Yes, I agree with you,   I will change  the name of function killme

Aaah, KillMe is a function in MyDll.dll?  In that case:

You issue the request, which arrives at the server via waa1gate.exe.

The function calls QUIT, which is an imperative command and does not allow
the application to gracefully exit.  This means that threads are terminated
immediately, therefore open sockets are abandoned.  Since it was not a
graceful shutdown, waa1gate.exe doesn't know the other end of it's socket
connection to waa1srv.exe is no longer valid.  This leaves waa1gate.exe
running indefinitely unless the web server imposes a timeout on it.

The solution to this is to make the shutdown more sophisticated so that
performs a graceful shutdown.  Put this lot in your code, and call the
KillMe function from your browser (as before, I'd suggest renaming this
function to something less easy to discover by accident).  The way it works
is by 'clicking' the close button on the WAA console dialog, then
'clicking' the 'Ok' button on the WAA Shutdown dialog.

Function KillMe( oHtml, oContext )
   local oThread := Thread():new()

   oHtml:put(GeneratePage())
   oThread:start({||____DeathByAnyOtherName()})
   return TRUE

STATIC Function ____DeathByAnyOtherName()
   local oWin := GetRootWin()

   PostAppEvent( xbeP_Close, NIL, NIL, oWin )
   sleep(10)  increase this if necessary (this should be enough)
   oWin := SetAppFocus()
   oWin:activate()
   return TRUE

STATIC Function GetRootWin()
   local oDlg := SetAppFocus()

   While !(oDlg:setParent() == AppDeskTop())
      oDlg := oDlg:setParent()
   Enddo
   return oDlg

Dedicated to the brave men who go down to the chips in C.

Pawel,

Of course, you need to call the function you called before, which will
launch WTRLaunch, which in turn will call the function I just gave you to
kill the application.

Hi Phil
Sorry, but it doesn't  work.

It's good for shutdown  WAA  from  outside   and  if  WAA  will be start 
manualy  on server   its work,
but I have to restart  WAA from outside.

it is from my code:

FUNCTION KillMe_first( oHtml, oContext )
RUNSHELL(" /C  D:\ALASKA\WAA1W32\SERVER\WTRLAUNCH.EXE ",,.T.,.T. )
oHtml:message('Information from Server' , 'WTRLaunch.exe  run on Server')
RETURN .T.

FUNCTION KillMe_second( oHtml, oContext )
   LOCAL oThread := Thread():new()

   oHtml:put(GeneratePage())
   oThread:start({||____DeathByAnyOtherName()})
RETURN .T.

STATIC FUNCTION ____DeathByAnyOtherName()
.
  here is your code   ( clear )

Well, everything looks Ok during the shutdown phase.

KILLME_FIRST has launched WTRLaunch, which then calls KILLME_SECOND.  Both
functions seem to end properly.

WTRLaunch obviously launches WAA again, but for some reason the gateway
seems to be blocked.  As for the error "gateway could not be reached", I'm
not sure where that comes from, because WAA does not know where the gateway
is.  All it can do is open a listening socket on the port named in the
environment (via the SET WAA_PORT= line in startwaa.bat).

As a first step to solving this error, what happens if you launch WTRLaunch
from the command line while WAA is running?

Phil Ide
